Using split with Nokogiri?

I am using a site's API to retrieve the following information:

5097,2593,1289766548 1541,99,65990390 934,99,73230517 3055,99,62377700

2577,99,24367856 603,99,34401457 1556,99,24433483 1115,99,22150489
1365,99,23373048 4889,120,121954995 10957,97,10702990 -1,-1 -1,-1
9460,3985121 -1,-1 -1,-1 25908,1608 17180,1538 19932,1519 33486,1651
-1,-1 2589,401 14280,1262 -1,-1 -1,-1 -1,-1 34212,360000 -1,-1 -1,-1 -1,-1

Note that the numbers are in sets of 3, separated by commas, then a space, then to the next set. 

xxxx,xxxx,xxxxxxxxxx yyyy,yy,yyyyyyyy zzzz,zz,zzzzzzzz

Here is my controller:

class PagesController < ApplicationController
  def home
    require 'open-uri'

    @username = "brink"
    @url = "http://hiscore.runescape.com/index_lite.ws?player=#{@username}"
    @doc = Nokogiri::HTML(open(@url))
  end

  def help
  end
end

Here is how I am putting out the information in the view:

<h1>Welcome to xpTrack</h1>

<p>
  <%= @username.capitalize %>
</p>

<%= @doc.text %>

Is there a way for me to create an array that splits at each space between each set of numbers? I have tried:

@stats = @doc.split('\n'), but that returns:

undefined method `split' (some Nokogiri error)

Don't use Nokogiri unless you expect XML or HTML. Just use open().read to get a string, and split it up.

Also, I suspect .scan(/(\d+),(\d+),(\d+)/), or some variation thereof, will work better than split.

You can try:

# split on spaces
@stats = @doc.text.split(' ')
# => ["xxxx,xxxx,xxxxxxxxxx","yyyy,yy,yyyyyyyy","zzzz,zz,zzzzzzzz"]

# split on spaces and then on commas
@stats = @doc.text.split(' ').map { |a| a.split(",") }
# => [["xxxx","xxxx","xxxxxxxxxx"],["yyyy","yy","yyyyyyyy"],["zzzz","zz","zzzzzzzz"]]
